BACKGROUND

1. Technical Field

The exemplary disclosure generally relates to a fastening structure used in a portable electronic device.

2. Description of Related Art

In assembling electronic devices, many subsidiary pieces need to be secured to a main housing of the electronic device. A typical method uses screws to fasten the subsidiary piece to the main housing. However, because most of the subsidiary pieces are thin and usually made of plastic, and due to the fragile nature of plastic, it is difficult to maintain a tight engagement between the subsidiary pieces and the main housing with screws.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

FIG. 1 shows an exemplary embodiment of a portable electronic device 100 with a fastening structure 50. The portable electronic device 100 includes a cover 10 and a main body 20. The fastening structure 50 includes a plurality of latching members 30, a plurality of latching portions 22 and a plurality of hooks 122, wherein the latching portions 22 are formed on the main body 20 and the hooks 122 are formed on the cover 10.

The cover 10 includes two opposite side edges 12. The hooks 122 are positioned at the two side edges 12.

The main body 20 includes two opposite sidewalls 21. The latching portions 22 are formed at the two sidewalls 21. Each sidewall 21 includes a top surface 211. The top surface 211 is recessed at one side and a flange 212 is formed at another side. Also referring to FIG. 2, each latching portion 22 includes a frame 221 integrally formed with the sidewall 21. The frame 221 defines a receiving cavity 222 through the sidewall 21. The flange 212 is partially cut to form two bars 224 at two sides of each frame 221 correspondingly, and a cutout 223 is defined in the sidewall 21 beneath each bar 224.

Referring to FIG. 3, each latching member 30 includes a middle plate 31 and two extending plates 33 positioned at opposite sides of the middle plate 31. A curved plate portion 32 connects the middle plate 31 and each extending plate 33, wherein a notch 334 is defined between the middle plate 31 and each extending plate 33. The middle plate 31 is bent at an end thereof to form a locking portion 311. Each extending plate 33 is bent at an end thereof to form a fixing portion 335. The locking portion 311 and the fixing portions 335 are hook shaped. A resisting plate 336 extends from each extending plate 33 at angle toward the fixing portion 335. In this exemplary embodiment, each resisting plate 336 is formed by cutting a corresponding extending plate 33 along a broken line beneath the fixing portion 335.

Referring to FIGS. 4 and 5, to attach the latching members 30 to the latching portions 22 of the main body 20, the fixing portions 335 respectively clasp the bars 224. The middle plate 31 is received in the receiving cavity 222. The resisting plates 336 are pushed into the cutouts 223 and resist the bars 224 to prevent the latching members 30 from separating from the main body 20.

Referring to FIGS. 6 and 7, to attach the cover 10 to the main body 20, the hooks 122 are respectively inserted into the receiving cavities 222. The hooks 122 slide along the locking portion 311 and the main plates 31 are pushed outward by the hooks 122. When each hook 122 passes its respective locking portion 311, the main plate 31 rebounds to its original shape and the hooks 122 are locked by the locking portions 311.

It is to be understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
